Description

[Detailed Description of the Invention] 3. Detailed Description of the Invention (Field of Industrial Application) This invention relates to a method of constructing architectural concrete blocks such as three-core cavity blocks and formwork blocks.

(Prior art) When constructing architectural concrete blocks such as three-core blocks and formwork blocks, conventionally, the above-mentioned architectural concrete blocks were placed at the site where the target structure was constructed.
While stacking them one by one, interpose a joint adhesive such as cement mortar to a thickness of about 1 CI 11 in the adjacent parts on the top, bottom, left and right,
After reinforcing the blocks horizontally and vertically as necessary and stacking them to a desired height and width, fresh concrete was poured into the cavity of the above-mentioned architectural concrete block and allowed to dry.

(Problem to be solved by the invention) Conventional construction methods should construct the desired structure.

At the site, construction concrete blocks were stacked up one by one while applying adhesive for joints, which required skill for each task, took a long time to work on the construction site, and the construction period was easily affected by the weather. There was a pause.

The present invention provides a construction method that requires little stacking of building blocks at a construction site, shortens the construction period, and does not require skill for construction at the construction site.

(Function) The process of forming panels can be carried out in a factory, such as a factory for manufacturing concrete blocks for construction.

These factory-produced panels are transported to the target construction site and erected, and the spaces between adjacent panels are filled with joining blocks.
By filling the gap for filling the bonding agent in the front surface of the spacer with the bonding agent, it is possible to obtain a structure with the same appearance as when building concrete blocks are stacked one by one at a construction site using the conventional method. After reinforcing the cavity of the architectural concrete block as desired, the fresh concrete block is poured into the cavity and dried. In addition, when using formwork blocks with horizontal grooves on both upper and lower surfaces or on one side or three-core hollow blocks for horizontal reinforcement as concrete blocks for construction, vertical grooves are Directional and lateral reinforcement is possible.

(Example) The architectural concrete block 1 shown in Fig. 1 is a formwork block, and has a rectangular front plate part 1a and a rear plate part 1b, and two partition wall-like joints having a 7-shaped recess at the top and bottom. Part 1
